PK Syntax:
    Because we have switches like -s [optional filename]
    you can't have more than one switch on the command line
    at once.  This is because it's not possible to differentiate
    whether:

        pk -s -rn 

    Means 'save a file named "-rn"' or is two commands.
    It's easy to check that the 'filename' isn't '-rn'
    but then you have to do all permutations of command line
    possibilities, and keep it updated if ever there is more
    commands added the the PK module.


New 'VIC' Job:
   Increment global counter => produce new id #
   create new 'room' directory
   create a PK object, save it to that room dir


PK File Format
    Did away with the whole '2nd line' bit.
    Except for 'KE', you have 3 bits seperated by ';'.
    SF/IQ/ID running stacks are comma seperated rather than
    having one on the first line then '  : ' rest,rest,rest
    Changed to just comma seperated.
    Allowed blank lines and '#-style' comments in column-0
